Screening for asymptomatic Chlamydia trachomatis, Neisseria gonorrhoeae, and Mycoplasma genitalium in medical students in Barcelona

Objectives: No previous studies had been performed on asymptomatic sexually transmitted infections (STIs) in Spanish university students. Therefore, the aim of the study was to determine the prevalence of Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), and Mycoplasma genitalium (MG) in this group. Material and Methods: All medical students were invited to participate in the study between September 2017 and June 2019. First-void urine specimens were collected from men and vaginal swabs from women. Results: Four females had positive results. The prevalence of CT and MG in women was 4.0% and 2.4%. All individuals with positive results had stable partners. CT infection was associated with having stable and sporadic sexual partner in the previous year. The frequency of positive results was higher in those women who had sought an app-based sexual partner. Conclusion: The prevalence of asymptomatic STI in medical students was similar (rather than lower) to that in same age individuals in the area. Medical knowledge might not protect from STI acquisition.
